See-saw swing apparatus

ABSTRACT

A pair of disc-shaped seats are supported in a horizontal relationship by a suspended cable having each of its ends attached to the central portion of a seat. The cable is threaded over a pair of overhead supported, horizontal disposed pulleys. The cable, pully and seat arrangement is supported such that any downward movement of one seat produces an upward movement of the other seat. The seats are suspended for simultaneous uphorizontal and down-horizontal movements.

3 Claims, 3 Drawing Figures SEE-SAW SWING APPARATUS SUMMARY OF THEINVENTION The invention is directed towards a swing which combines thebest features of a swing and a see-saw. The object of the invention isto provide a swing which allows each of a pair of users to swing freelyin two dimensions, and at the same time allows one user to raise orlower the height of the other users seat by lowering or raising theheight of his own.

Thus, a like pair of discs are supported by a single cable which isattached at each end to the center of a disc.

The cable is supported by a frame which allows the cable to move in amanner that the downward motion of one of the seats moves the cable tocause a like upward motion of the other seat. Because the ends of thecable hang downwardly under the influence of gravity, each disc is freeto rotate about the cable and to swing in any vertical plane. When apair of users are sitting on the seats, one user can raise or lower theseat height of the other user by lowering or raising his own seatheight.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to thedrawings, a cross bar is disposed in a horizontal plane and supported ateach end by an A shaped support 20. The cross bar supports a carrier 30which supports two like pulleys 40 in a manner that they are free torotate in a common vertical plane. A cable 50 is supported by thepulleys and is run through two guides 60, each of which takes the formof a hollow elongated cylinder with a central vertical bore in which thecable is disposed. The ends of the cable are attached to the centers ofeach of two like discs which serve as seats.

While the invention has been described with detailed reference to thedrawings, the protection sought is to be limited only by the terms ofthe claims which follow.

I claim:

1. A swing comprising:

a frame having a pair of spaced apart vertically upstanding supports andan elongated horizontal support bar connected at its ends to the upperend of the supports;

a pair of spaced apart pulleys being attached to said support bar andbeing disposed in a common plane;

a cable, said cable being passed over said pulleys such that each of itsends is freely suspended below a respective pulley; and

a pair of seats, each end of said cable being centrally attached to aseat such that each seat is free swinging when supported by said cableand any upward movement of one seat produces a corresponding downwardmovement of the other seat.

2. The swing of claim 1 wherein the seats are disc shaped.

3. The swing of claim 1 wherein said pulleys are disposed perpendicularto said horizontal support bar.

1. A swing comprising: A FRAME HAVING A PAIR OF SPACED APART VERTICALLYUPSTANDING SUPPORTS AND AN ELONGATED HORIZONTAL SUPPORT BAR CONNECTED ATITS ENDS TO THE UPPER END OF THE SUPPORTS; A PAIR OF SPACED APARTPULLEYS BEING ATTACHED TO SAID SUPPORT BAR AND BEING DISPOSED IN ACOMMON PLANE; A CABLE, SAID CABLE BEING PASSED OVER SAID PULLEYS SUCHTHAT EACH OF ITS ENDS IS FREELY SUSPENDED BELOW A RESPECTIVE PULLEY; ANDA PAIR OF SEATS, EACH END OF SAID CABLE BEING CENTRALLY ATTACHED TO ASEAT SUCH THAT EACH SEAT IS FREE SWINGING WHEN SUPPORTED BY SAID CABLEAND ANY UPWARD MOVEMENT OF ONE SEAT PRODUCES A CORRESPONDING DOWNWARDMOVEMENT OF THE OTHER SEAT.
 2. The swing of claim 1 wherein the seatsare disc shaped.
 3. The swing of claim 1 wherein said pulleys aredisposed perpendicular to said horizontal support bar.
